Open publisher page 0 citations

Abstract

PP-g-MAH-a kind of polypropylene(PP) grafted with maleic anhydride(MAH) was prepared in a solid phase reactor by the technology(degrading PP initially and then grafting the resultant), and characterized by Fourier transform infrared spectroscopy and differential scanning calorimetry.The effects of reaction time,initiator dosage,reaction temperature and monomer concentration on graft ratio were studied.The results showed that the graft ratio of 2.85%could be acquired under the following conditions:reaction time 2.5 h,grafting temperature at 120℃,initiator mass fraction 4%and MAH mass fraction at 14%.
